Specification of Letters Patent.

Application led February 7, 1905. Serial No. 244,576.

To 11]/ mh/0171 it mfr/U concern.-

Be it known that I, JOHN R. CARTER, of Augusta, in the county of Bracken and State of Kentucky, have invented certain new and useful Improvements in VVashing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in washing-machines, the object of the invention being to provide an improved arrangement of the operating parts for reciprocating the rubbers, particularly the upper rubber, whereby a light-running and powerful machine is secured.

Wvith these objects in view theinvention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure l is a view in longitudinal section illustrating my improvements, and F ig. 2 is a top plan view of the rubbers.

1 represents the body or tub supported on legs 2 and having the lower reciprocating rubber 3, pivotally supported therein.

la represents the cover, hinged at one end to the body and provided with verticallyelongated bearings 5 to receive trunnions 6 at opposite sides of the upper rubber 4, and springs 7 are provided to elastically hold the upper rubber down on the clothes. Supported on the cover 4a is an operating crankshaft 8, connected by a pitman 9 with the end of lower rubber 3.

On a cross-bar l0, secured to upper rubber 4 between the trunnions 6 and the end of the upper rubber 4 farthest from the crank-shaft, is a standard 1l, movable in a slot 12 in the cover and connected by a pitman 13 with i operating crank-shaft, so that when the crank-shaft is turned the upper and lower rubbers will be simultaneously reciprocated in opposite directions.

By locating the standard 11 at a point between the pivotal support of the upper rubl ber and the end thereof farthest from the crank-shaft a greater leverage and increased power is secured from the crank-shaft without diminishing the stroke of the rubber, and

I the pivotal connection between said standard and the pitman moves through a different arc of a circle', through which it is more easily moved than would be the case were the standard located in vertical alinement with the pivotal point of the rubber, as heretofore. For example, if the standard is located in alinement with the pivotal support its upper end, to which the pitman is connected, moves down from each side of the central point and requires considerable power on the pitman when directed against the lever in its lowest position inclined toward the crank-shaft to force it in the opposite direction, which movement raises the pivotal point against the natural tendency of gravity of the crank (if the driving power be removed) to force it down.

Vith the improved construction shown the upper end of the standard moves in a totally different arc from that above described, as its upper end swings from the highest point of its throw to its lowest point in a direction away from the crank and never drops below the highest point of its throw toward the crank. Then, again, bylocating the standard at one side of the pivotal point when the pitman exerts a pulling strain on the standard during its stroke toward the crank the tendency is to slightly lift the rubber and make the stroke a light one as compared with the stroke in the reverse direction, in which a downward pressure is applied in addition to the reciprocating movement and exerts increased rubbing action on the clothes during this stroke. I-lence it will be seen that the entire stroke of the upper rubber in one direction is heavier and more powerful than the other stroke and secures the action such as attained in ordinary hand-washing on a washboard.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a washing-machine, the .combination With 'a tub or body, a crank-shaft, and an osciliatory rubber having a standard on the side thereof remote from the crank-shaft, of a pitman between the crank-shaft and standard, the connection between the pitrnan and standard being in approximately the same horizontal plane with the crank-shaft.
